The Chinese embassy in Ottawa said Meng was arrested despite her “not violating any American or Canadian law,” adding that the arrest constituted a breach of her human rights.

“The Chinese side has lodged stern representations with the U.S. and Canadian side, and urged them to immediately correct the wrongdoing and restore the personal freedom of Ms. Meng Wanzhou,” an embassy spokesperson said.

Meng’s arrest, which was first reported by the Globe and Mail, comes less than two months after U.S. lawmakers sent Prime Minister Justin Trudeau a letter urging Canada to ban Huawei’s equipment from Canadian wireless networks.

In a letter obtained by Global News, Republican Sen. Marco Rubio and Democratic Sen. Mark Warner conveyed “grave concerns” over the possibility that the Chinese government might be using Huawei equipment to spy on and interfere with foreign governments.

“There is ample evidence to suggest that no major Chinese company is independent of the Chinese government and Communist Party,” they wrote.

U.S. authorities have been probing Huawei’s alleged shipping of American-origin products to Iran in violation of U.S. export and sanctions laws, sources told Reuters in April.

Meng, the 46-year-old daughter of Huawei founder Ren Zhengfei, has previously been suspected of involvement in Huawei’s alleged ties to Iran.

In 2013, Reuters revealed that Meng served on the board of Skycom Tech, a Hong Kong-based firm that attempted to sell embargoed computer equipment to Iran’s Mobile Telecommunication Co. in violation of trade sanctions.

That is widely seen as part of a broader effort by Washington to respond to intensifying competition with Chinese technology industries that Trump says benefit from improper subsidies and market barriers.
